There have been quite a few news stories about how the lockdowns in different parts of the world have made significant impacts on air quality.
Major cities in North America, Europe, and Asia experienced unprecedented decreases in nitrogen dioxide levels and particulate matter pollution.
Scientists can now collect data and experiment, and not just use models and projections.
Facebook, Instagram and other social media feeds are full of photos of where folks discovered they could see snow-capped mountain ranges for the first time, in a long time, previously obscured by smog.
Although temporary, it does highlight the human impact on air quality, and provides a glimpse of how we can change things for the better as emission standards improve, we change our habits, and alternatives to the combustion engine become more prevalent.
It will be interesting to see if there will be a push towards keeping the air cleaner as things open back up again.
Beijing is a fine example. The air was thick as soup and toxic before the 2008 Olympics. They tightened up pollution controls and cleaned things up for the games, and it is much better today.
Some positive news during a difficult situation.
